Application filed August 24,1911. Serial No. 645,895. I

To all whom it may concern: i

Be it knownthat I, Hnnson lV.}lAKES,EL citizen of the United States.residing at 'Millbury, in the county of Worcester and Ccmmcnwealth ofMassachusetts, have invented a new and useful ImprovementinSelf-Threading Loom-Shuttles, ofwhich the following is aspecification,accompaniedby drawings forming a part of the same.

My invention, relates: to what are technically termed self threadingshuttles for looms, in whichithe thread may be carried by hand from thebobbin in the bobbin chamber by a continuous passage to the eye of theshuttle, with the'opening, of-the eye provided at the delivery end withmeans for preventing the accidental escape of the thread from the eye,and. with the shuttle also provided with a device for preventing theballooning of the thread;

The objects of myimprovement are to provide the connectingpassagebetween the bobbin chamber "and the eve arranged to facilitate thethreading and operation ofthe to simplify the entire construction of theshuttle; to simplify the construction of the shuttle and the eye toaid'in their assembly; I

to, provide a simple and easily attached device for the prevention oftheballooning of l the thread, arranged to accomplish the easy shuttle;Fig. 2.is a view of one side of the aline nent: with the tip of thethreading and operation of the shuttle; and

threading and delivery apparatus of the shuttle. l accomplish theseobjects by the mechanism illustrated in the accompanying. 1 drawing, inWl1lCh i Figure 1 is a plan view of my improved delivery end of the sameshowing the delivcry eye ofthe shuttle andFig. 3 is a View 40,, i is asimilar sideview to Fig.2 witha portion of the shuttle shown in centralsection; Fig. 5 is a transverse section of the shuttle c of the oppositeside of the same end; Fig. a

on the line 5+5 Fig. 1; Fig. 6 is a detached perspective view of theantiballooning device; Figs. 79 inclusive are detached perspective andside views of the delivery eye andl ig. 10 1s a side view of amodification of the same. Similar, reference characters refer to larparts in the different figures.

In the shuttle'body l of the vusual construction is the bobbin chamber 2with a recess 8 at the delivery end. The recess 3 t r ar end opens direcv t he in simibobbind. Transverse to the body of the shuttle andcommunicating with the forward end of the recess 3 is an a pproxiinatelycylindrical opening '5 extending entirely acrcss the shuttle, as shownby dotted lines p q of e rs Est 5 Patented Jan. 18, 191%, p

inFig. l, and arranged to receive the cylindrical eye 7 which isprovided with a radial lip 8 held in a radial slot 9 at the side of theopeninga} to prevent the rotation of the eye '7, The eye 7 is insertedin the transverse opening 5 at the end 10, shown in Fig. 9 extendsentirely, across theshuttle bodyand is arranged to deliver the thread onthe op posits side at the end 11, as shown in lig. 2.

Attentionis called to the fact that the'opening 5 is cylindricalentirely across the shuttle body, having no obstruction to interferewith its formationor the construction of the radial slot 9. a t r i Theeye 7 is made of sheet metal in cylindrical form andis provided withtransverse slot 12, wh ch is arranged Jto coinc de with the axis of therecess 3 when the eye isinposition in theshuttle, as shown nFig. 5. Fromnear the bottom of the slot 12 to the delivery end 11 of the eye;

is a longitudinal triangular space 12 commun cating w th an oblique slot13 WlllCh is arrangedat the delivery end 11 to open at the top of theeye 7, allowing the thread from the slot 12 'upwardinto the eye 7,

thereby facilitating the threading of the shuttle. One side of the sheetmetal composing the eye 7 is formed with the radial cl p 8 toward therear of the eye, arranged;

to enter the slot 9 and prevent the eye from turning. The passage of thethread into the transverse slot 12 is provided for by the opening 14inithe radiallip 8, as shown in in the operationot' threading to bedrawn;

Fig, 9, inwhich the slot 12 is partially@ "being tln'eaded is preventedby an overhanging shoulder formed by the edge 16,

self;

Fig. 2, of the shuttle body, which is arranged to pass in front of thedelivery opening slightlybelow the upper edge and thereby prevent; theescape of the thread fr m the yebvan pwa d m men This fil p lldfi fupper edge lit at the. 1 92i zontal slot 17 in the shuttle body in frontedge 16 in front of the eye 7 is not employed for-this purpose, so thatthe formation of of the eye 7 forms an obstruction to the boring of theopening 5' and also to the convenient excavation of the radial slot 9.In the present shuttle theshoulder of the the transverse opening 5 andthe .slot 9 is facilitated, as already stated. V p I The upward movementof thejthread from the eye 7 in my device is prevented as follows':A narm 18 is extendedv outward I from the sheet .metal eye 7 at thedelivery end 11 which supports a'semicircular plate 19, Fig. 7, which,being held at a distance from the eye 7', allows the insertion of thethread from the oblique slot 13 over the upper curved portion andbeneath the lower edge 21 of the plate 19, by which the thread isprevented from upward escape as it is delivered from the eye.

The antiballooning device is shown in perspective in Fig. 6 and isarranged tobe inserted in the recess 3 in front of the bobbin 1. Theantiballooning device consists of parallel plates 22 and 23, separatedby a less distance than the width of the recess 3 and provided at theirupper ends with horizontalflanges 24, arranged to be inserted in theshuttle body on opposite sides of the recess 3. The plate 22'is providedwith a curved tongue '25 arranged tocross the distance between theplates 22 and 23 and enter a mortise 26 inthe oppositeplate 23. In thethreaded shuttle the thread passes between the plates 22 and '23 beneaththe tongue 25, by which the ballooning of the thread is prevented.

' The upper edge 27015 the recess 3 is chamfered and the thread passesfrom the antiballooning device shown in Fig. 6 through the customarycurved diagonal slot 28 and 'the horizontal slot 17 into the transverseslot 12 in the eye 7, from which it is delivered from the shuttlethrough the eye 7 beneath the lower edge 21 of the'plate 19,

by which its upward escape from the eye 7 is prevented. The outer end 29of. the tongue 25 is curved to cross the space 30 between the plates 22and 23 and extend in the mortise 26. The tongue 25 is narrower ment ofthe thread from the slot 12 to the interior of the eye 7 in threadingthe shutt tle. By opening the oblique slot 13 at the top of the eye 7,the lower half of the eye is arranged to be solid and free from anyopeningsor shoulders tending to engage the thread as it is deliveredfrom the eye. The eye 7 is constructed of sheet metal rolled intocylindricalforin in cross section, but having thefdelivery end slightlysmaller than the opposite end, giving a slight taper to allow it to bedriven into' and fittightly in the hole inv the shuttle.

To thread the shuttle, the thread is taken 2 from the bobbin 41 anddrawn around the tongue25 through the'mortise 26 into the" space 30below the tongue 25.

From the space 30 the thread is passed through the diagonal slot 28 andthe horizontal slot 17 into the transverse slot 12 in the eye 7 inalinement with the space 30. From the slot 12 the thread is passedthrough'the oblique slot 13 into the interior of the eye 7, then aroundthe plate 19 and below the lower edge 21 where it is in ered from thebobbin. 7
